Hello,I am new in Real Basic, coming from VB6, i am converting Vb6 applications to RB2012.RB2012 does not have time ctrl, I have found free open source class for time ctrl, does any one knows how to build controlwith .rbo file ?regards.

I've never used or heard of this class, so I can only suggest reading any accompanying documentation. Most likely, the class has been added to the list of controls available to be dropped onto a window in the window editor (you may need to tell the control list to show all available controls.)
